The rotating shaft 5 is rotatably mounted on the frame 1 and has an ejector surface abutting against the upper end of the ejector 4. The control main board 73 is electrically connected to the motor 71, and is configured to control a rotation angle of the motor 71 to adjust a pressing degree of the printhead module 2.
When the print head regulating device is in an initial state, the elastic member 3 is in a compressed state, and the top plate 21 is lifted up under the action of the elastic member 3.
When the printing head regulating and controlling device compresses the printing head 24, the control main board 73 controls the motor 71 to rotate in the forward direction, the motor 71 drives the rotating shaft 5 to rotate in the forward direction, the rotating shaft 5 pushes the pushing piece 4 to move downwards through the pushing face, and the pushing piece 4 further pushes the top plate 21 downwards, so that the printing head 24 is compressed. The top plate 21 also applies a positive torsion to the elastic member 3 through the housing 23 at one end of the connecting shaft 22, so that the elastic member 3 is compressed and deformed. In addition, the control main board 73 can control the angle of the forward rotation of the rotating shaft 5 by controlling the motor 71, and further control the downward movement distance of the pushing member 4, thereby adjusting the degree of pressing down the print head 24.
When the printing head regulating and controlling device loosens the printing head 24, the control main board 73 controls the motor 71 to rotate reversely, the motor 71 drives the rotating shaft 5 to rotate reversely, the elastic part 3 pushes the connecting shaft 22 to rotate reversely through the shell cover 23, and the connecting shaft 22 further drives the top plate 21 to lift up, so that the printing head 24 is loosened. Meanwhile, the top plate 21 also pushes the pushing piece 4 to move upwards for resetting.
